What Are the Most Important Components Of A Cold Storage Room?

Cold storage is a facility that’s used to store food items such as fruits, vegetables, fish and meat. The temperature of the rooms can be adjusted to meet the required specifications of the individual products being stored.

Cold storage facilities work by maintaining a temperature around freezing, which is ideal for storing all kinds of food. A cold storage room has several key components:

Condensing Units


The compressor is a big machine that makes cold rooms work. It’s what runs the refrigerant through the system and turns it into liquid, so that the cold room can keep things cool. The compressor needs a lot of energy to run. It uses up almost all of the power in a cold room. It takes hot air in and turns it into cold air.


A condensing unit uses the high-pressure refrigerant and circulating water from the compressor to remove heat from the system. It changes the refrigerant from a gas to a liquid by absorbing heat, which cools both the refrigerant and circulating water. A condenser is like a radiator for your car, which keeps it from overheating. The efficiency of your condenser determines how well your cold storage plant cools its contents.


Once the refrigerant leaves the condenser, it passes through a component called a receiver. The high-pressure liquid refrigerant is stored in the receiver. The refrigerant then goes to an expansion valve where pressure and temperature are lowered.

Expansion Valve:

A small valve inside the system called an Expansion Valve reduces the temperature and pressure of the refrigerant. To do this, a throttling device inside the valve restricts the flow of gas as it passes through. This causes friction that produces heat and lowers both the temperature and pressure of the gas. The result is that refrigerant in the Receiver will have a higher pressure than that in the Evaporator.


The Evaporator is a component that lowers the temperature of items in a refrigerator. It takes heat from the storage compartment or atmosphere that is supposed to be cooled, converts it into a gas by boiling the liquid refrigerant and then transfers the gas to a condenser. The gas cools while moving through the condenser and goes back to its liquid form. The liquid evaporates again and continues to cycle through this process until it reaches the desired temperature inside the refrigerator.


The cooled air is spread across the room by a fan, which creates a convection process. This cools down the room to the desired temperature.

Everything You Need To Know About Condensing Units

Also known as compressor unit, condensing unit is the most essential component of a cold room system. A compressor unit usually is a high side assembly of a refrigeration unit. It’s an assemblage of fan motor, condenser, compressor, controls and a mounting plate. It perform the function of a heat exchanger to cool down and liquefy the approaching coolant vapour into liquid and a fan for blowing outside air via the heat exchanger section to cool the inside of the refrigerant. Condensing units can be available in different designs and sizes ranging from small domestic appliance units to pretty large industry units employed in food & manufacturing processes.

Condenser units enable living & working in areas that were once known to be uninhabitable, heat pump offers efficient heating for temperate locales and refrigeration prolong the lifespan of unpreserved food.

What To Consider When Selecting Cold Room Storage?

When you are looking for freezer room storage space, you are likely to have a specific need for the cold storage unit. There are a few things that you need to look out for to make sure that you choose the right cold storage space that is perfect for your company, or you run the risk of cold storage not being adequate, leading to the loss of a significant amount of stock.

Purpose of the cold room

For what purpose do you wish to buy a freezer room? D you need a commercial cold room for the hospitality industry needs or a laboratory cold room for pharmaceutical requirements?

Industrial freezer rooms not only safeguard farm produce, seafood, pharmaceuticals, and other agricultural supplies, they can also preserve operational IT servers and equipment whose lifespan can get affected adversely by the heat they generate.

Food processing, chemical industry, oil and gas industry, manufacturing industry, hospitality, and supermarkets find wide applications of freezer rooms that are durable, easy-to-clean, and easy-to-use.

The capacity of the cold storage

Your operational prerequisite should determine this aspect. The size of the cold storage should exceed the bulk of stock you wish to preserve. it should have ample space for shelves, racks, airflow, aisle space to roll bulk of food items in and out, etc.

The gap between the wall, ceiling, and volume of the products – all these aspects need attention. Cold rooms manufacturing companies recommend installing larger cold rooms than installing several smaller cold storage to provide the equivalent chilling facility.

Buy perfectly-engineered freezer rooms at Africhill and rest assured that they won’t break your bank.

When Do You Replace Refrigeration Condensing Units?

Commercial refrigeration units are used for different applications from medium to large. They require a sturdy and functional condensing unit. This unit contains components like fan motor, controls, compressor, condenser etc. It uses as a heat exchanger to cool down and condensate incoming refrigerant vapor into liquid. The refrigeration system has top quality fan that helps in blowing surrounding air through the heat exchanger to cool the refrigerant present inside.

Have you decided to replace condensing units instead of fixing them? Fixing problematic issues can be a bit hassle. There are so many signs your condensing units need replacement. Some of the best signs are discussed below:

Different factors can result in external condensing unit to stop working. The common reasons include improperly working compressor and coil. Compressor failure is one of the most common reasons behind the replacement.

Compressor is the heart or engine of your commercial refrigeration unit. The overall cost of compressor replacement and installation will outweigh the cost of a new condensing unit. The cost remains constant in most residential systems.

You should focus on preventive maintenance regularly, if you really want to avoid failing condenser. It’s highly suggested to take proper care and maintain the condensing unit to ensure the durability and cost savings. This way, you won’t need to replace the system often.

Usually you will see failures because of untimely maintenance and dirty condenser coils. They are major reasons behind the failures. However, replacing a compressor is expensive especially if your condensing unit is an R-22 system.

What are the factors behind condensing unit failure?

  • When making a decision on a condenser which is holding on barely, you should consider the operational time and working condition.
  • You should pay more attention to the time, electric issues and use which significantly impact on your unit’s working capacity. If one of these parts doesn’t come under the guarantee period, it’s better to contemplate the entire unit replacement.
  • If you’re using condensing units having compressor failures, you should fix them better. It’s suggested to replace the unit as soon as possible.

Why do you replace condensing unit?

Please keep in mind that repair cost is more than the price of a new unit. You should think about thoroughly and do research on replacement options.

It’s better to change the system to adapt the latest technology and advancement, if you’ve the more aged or ten years old equipment. By replacing the unit, you will get energy savings, possible refunds and assurance of another system.

Most commercial facilities owning refrigeration units put off the decision to replace the equipment instead of fixing them. They decide to consider more consistent and highly efficient equipment with state-of-the-art features for better use.
